Abstract: A power tool comprises a housing, a motor assembly and an impact assembly configured to be driven by the motor assembly. The impact assembly comprises a hammer defining a hammer chamber therein and an anvil at least partially disposed in the hammer chamber and configured to rotationally drive an output shaft. The anvil comprises a body portion, an anvil chamber defined therein, and a reciprocating member configured to selectively move radially outwardly relative to the body portion to be selectively impacted by an impact member of the hammer so that the hammer selectively imparts rotational movement to the anvil. The anvil includes an active valve configured to control discharge of fluid from an anvil chamber to the hammer chamber. The active value variably opens based on variance of one or more physical characteristics of the fluid (e.g., at least one of volume, temperature, pressure, or viscosity of the fluid).

Abstract: An actuator assembly for a power tool includes an actuator with a permanent magnet. The actuator is moveable between a first position for a first mode of operation, and a second position for a second mode of operation. A first positioning member is adjacent the first position composed of a ferromagnetic material to attract the permanent magnet. A second positioning member is adjacent the second position and composed of a ferromagnetic material to attract the permanent magnet. An electromagnet may be energized to move the actuator between the first position and the second position. When the electromagnet is not energized and the actuator is in the first position, the actuator is retained in the first position. When the electromagnet is not energized and the actuator is in the second position, the actuator is retained in the second position. When the electromagnet is energized, the actuator moves between the first and second positions.

Abstract: An electronic control module provides dual insulation layers between an internal line voltage and a separate tool housing that serves as a heat sink, thereby allowing versatility in mounting the electronic control module within the tool housing interior, and thereby also eliminating the risk of electrical shock to a user making contact with an exterior tool housing surface. The control module includes a power device, connected to a line voltage, and a thermal pad. The power device provides a first layer of electrical insulation between the line voltage and an external tab of the power device while the thermal pad provides a second layer of electrical insulation. The combined first and second layers provide a minimum amount of electrical insulation between the line voltage and the tool housing thereby preventing electrical shock. Alternatively, the thermal pad is provided between the control module and the tool housing.
